Diamond Energy is a Victoria-based national electricity retailer focusing on serving customers who have solar panels. and ensuring that the process of grid connection and afterwards is as smooth and efficient as possible. The company has been providing electricity from renewable sources to their customers since 2007, and has added 3500 home solar PV systems to its generation/retail portfolio to date, with this number still growing.

Choosing the right electricity retailer for solar power

Selecting the right electricity retailer is crucial to ensure customers get the most out of their solar pv system investment. The process of connecting a solar system to the grid is highly specialised, so it is advisable that customers fully understand peak and off-peak pricing, solar feed-in tariffs, hidden fees and charges, and the retailer’s ability to efficiently service a customer’s setup and ongoing requirements.

What does Diamond Energy offer its customers?

Diamond Energy is set apart from other electricity retailers primarily in 2 ways: 1) They offer better deals for customers with solar PV systems, and 2) They balance customer consumption with generation sourced from low-carbon, renewable energy sources.

Diamond Energy Customer Service

All of Diamond’s retail customers have grid-connected solar PV systems, and the company aims to help these customers get the best out of their solar investments. With solar, the one of the keys to improved return on investment is to get grid-connected and start generating electricity as soon as possible after installation. The ideal electricity retailer to deal with would be one who provides a professional, experienced, dedicated team who actively follow up on all paperwork, including feed-in tariff paperwork, and who are knowledgeable about the process of managing meter changeover. Diamond Energy offers all of these things to its customers.

The company also promises:

-One of the highest Solar Feed-in Tariffs (including GST and dependent on qualification as per government legislation), with a top-up of 8 cents per kilowatt-hour available (read more below), plus solar-specific retail electricity rates

-No hidden costs to access Feed-in Tariffs (some retailers may charge up to $10 each time credit is paid out to customers)

-Diamond Energy only deals with solar customers

-Friendly, Australia-based, solar-specific customer care staff

-Feed-in Tariffs over $50 paid in cash every quarter

-3% direct debit discout with no paper bills (excluding discounts on any additional charges)

-Australian owned and operated, supporting regional communities

-Free web portal, offering remote monitoring capability available (for SA and QLD customers)

Victoria Transitional Feed-in Tariff: 33c/kWh and no hidden fees

Officially, Victoria’s Transitional Solar Feed-in Tariff guarantees customers of electricity retailers with 5000+ customers will be paid a minimum of 25c for every kilowatt-hour (kWh) that they feed into the electrical grid. Some electricity retailers offer a premium on top of the minimum rate in order to attract customers with solar power systems. Diamond Energy, who also offered an additional premium on the state’s now defunct Premium Solar Feed-in Tariff, currently offers 8c/kWh above the mandated 25c rate, meaning a total of 33c for each kilowatt-hour exported to the grid.

Diamond Energy’s 100% renewable generation portfolio

The balance of Diamond’s generation capacity comes from a variety of other renewable energy sources. The company owns and runs bio-gas to renewable energy plants (pdf) in Tatura and Shepparton, which convert methane from wastewater into renewable energy and have a total capacity of about 1MW. Diamond Energy is also in the process of developing Australia’s first wave farm in Port Fairy, Victoria. Once it is operational, Diamond energy will manage the grid connection and market the energy produced there, as it does with a number of the wind power generation units in its portfolio.

it seems that solar is no longer worth installing. currently sitting at 8ckw soon to drop to 6.2c kwh whats the point of that. people work from 8 to 5 so the whole day generating power that wont be used and just giving freely back to the grid. we are basically powering Australia and some one is sitting back reaping the rewards.

Hi Michael,

You are absolutely right that the feed-in tariff situation is not fair, but it’s the reality. You’d be surprised, though: Lots of folks are finding going solar a very worthwhile endeavour despite the poor feed-in rates.

We do our best here to make sure everyone is well-informed about what it means to go solar and how to get the most out of a system. What that means these days, with solar feed-in tariffs being worth so little as you’ve pointed out, is that any home or business that goes solar needs to aim to consume as much of their solar power as possible–which means using power when the sun is shining.

This, in turn, means understanding your daytime electricity usage pattern and accurately sizing your solar system to meet your daytime electricity needs.

So going solar makes sense, but those considering a system have to be smart about their approach. The first step is being well-informed about.

Hi there,

We thought it would be a good idea to install a 3kw solar panel system to our local scout hall. However, with the scout hall generally unused during the day when power is generated, and feed-in tariffs so low, is there any point??


Solar Choice Staff March 17, 2015 at 1:17 pm

Hi Jannene,

You’re right that it would most likely not be worth it to go solar for the scout hall. These days going solar is all about using your solar electricity while it is being generated – rather than allow it to be exported to the grid and ‘waste’ it.

If you could find a cost-effective energy storage system, then it might be worth it for you, but for most people energy storage is not yet worth the investment (although it’s getting close).

If you’re curious about checking out prices and talking to some installers about the case for going solar in your situation, you can always request a Solar Quote Comparison from us by filling out the form to the right of this page.
